Answers

Answer 1

Answer:

6 [tex]\frac{1}{12}[/tex] (6 1/12)

Question explanation:

First: 9 [tex]\frac{3}{4}[/tex] (9 3/4)

Convert any mixed number to fractions.

Then you initial equation becomes:

[tex]\frac{49}{4} - \frac{5}{2}[/tex]

(49/4 - 5/2)

Applying the fractions formula for subtraction,

(49 x 2) - (5 x 4)

4 x 2

98 - 20

8

= [tex]\frac{78}{8}[/tex]

(78/8)

Simplifying 78/8, the answer is:

9 [tex]\frac{3}{4}[/tex]

(9 3/4)

Second: 5 [tex]\frac{3}{4}[/tex] (5 3/4)

Convert any mixed numbers to fractions.

Reduce fractions where possible

Then your initial equation becomes:

39 - 4

4 - 1

Applying the fractions formula for subtraction.

(39 x 1) - (4 x 4)

4 x 1

39 - 16

4

= [tex]\frac{23}{4}[/tex] (23/4)

Simplifying 23/4, the answer is

5 [tex]\frac{3}{4}[/tex]

(5 3/4)

I hope this is correct, goodbye! - Answered by Lilo

Answer 2

Answer:

[tex]6\frac{1}{12}[/tex] yards

Step-by-step explanation:

Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

The amount ribbon she had at the beginning: [tex]12\frac{1}{4}[/tex]

The amount she used: [tex]2\frac{1}{2} +3\frac{2}{3}\\[/tex]

Our expression: [tex]12\frac{1}{4} -(2\frac{1}{2} +3\frac{2}{3} )[/tex]

LCM of 2, 3, and 4: 12

2:

2, 4, 6, 8, 10, 12, 14, 16, 18, 20

3:

3, 6, 9, 12, 15, 18

4:

4, 8, 12, 16, 20

[tex]12\frac{1}{4} -(2\frac{1}{2} +3\frac{2}{3} )\\\\\frac{4*12+1}{4} -(\frac{2*2+1}{2} +\frac{3*3+2}{3})\\\\\frac{49}{4}-(\frac{5}{2}+\frac{11}{3})\\\\\frac{147}{12}-(\frac{30}{12}+\frac{44}{12})\\\\\frac{147}{12}-\frac{74}{12}\\\\\frac{73}{12}\\\\6\frac{1}{12}[/tex]

Therefore, Marcella will have [tex]6\frac{1}{12}[/tex] yards of ribbons left.

Hope this helps!

Answer:

22

Step-by-step explanation:

Answer: 22ft^3

Step-by-step explanation:

First, find the volume of the little cubes that the rectangular prism can hold inside of itself.

The formula for volume of a rectangular prism is:

V = length x width x height.

= 1/2 x 1/2 x 1/2

= 1/8

Now, since the rectangular prism can hold 176 of these cubes, you need to multiply each cubes volume, 1/8, by 176. 1/8 x 176 = 22

Therefore, the volume of the box is 22ft^3

On a winter day, the low temperature in Anchorage was 23 degrees below zero, (in Celsius) and the low temperature in Minneapolis was 14 degrees below zero (in Celsius). Sophia wrote, Minneapolis was colder because: -14 < -23

Is Sophia correct? Explain your answer.

Answers

Answer:

Sophia is incorrect

Step-by-step explanation:

This is because if you looked a number line, -14 is closer to 0 than -23. So.. -14>-23

It is 37 because u do 23-23 which gives you 0, then you take away 0 and go down until -14, 23+14=37 so it is 37 Degrees Difference.

Answers

Answer:

D.

Step-by-step explanation:

The time goes up by 1 every time and the distance goes up by 500 every time. Lets lok at the relationship:

As seen in the graph, every minute she goes 500 ft. Theoretically, if we take half of the time to run then we must take half of the distance. This can be described as a distance/time relationship. So now with that knowledge, we loot at the 10-minute mark; she's currently at 5,000 feet so if she goes half the time more we are adding half the feet she runs per minute (250ft). Therefore the answer is 5,250 feet since we are adding 250(half the time she runs per minute) to 5,200 feet(how much she ran in  10 minutes)

Which of the following expressions could be used to find the sale price of an item that costs d dollars if it is on sale for 30% off?
0.7 d
0.3 d
30 d
70 d

Answers

Answer:

0.3 d

Step-by-step explanation:

A percent is basically the percent over 100

In this case, the item is 30% off so you can write 30% as a fraction like the following:

30/100

Now we can convert that to decimal

30/100 is also 0.30

Since there is no need for the extra zero in this case

the answer for this question is:

0.3 d

If the volume of a square-based pyramid is 300 cm cubed with a height of 9 cm, then what is the height of the base?

Answers

Answer:

9.4868 cm Rounded: 9.5cm

Step-by-step explanation:

V(Volume) = 1/3 x B(Base area) x h

300 = 1/3 x B x 9

10 x 1/3 = 10,3

300/10,3 = 90

B = 90^2

l(length of the base) = [tex]\sqrt 90[/tex] = 9.4868
